It would be nice to have more details about version of ReiserFS, what hash 
was being used, kernel version, hardware involved, and NFS or not 
(especially kernel NFSd)...

That said we use ReiserFS on our mail and on our NFS servers running a 
2.4.27 variant with about half a TB in NFS and about 120Gb in mail, no 
issues whatsoever.  We did have an issue with the CX200 that caused some 
corruption in the NFS stores once, but that's resolved now.  We were 
running old FLARE that caused the array to spit out multiple drives when it 
had a vault drive fail.
